摘要
In the centrosymmetic title complex, [Co(C18H12N5)2(H2O)2], the CoII ion is coordinated by two N,N∩-bidentate 5-(pyridin-2-yl)-3-[4-(pyridin-4-yl)phenyl]-1H-1,2,4-triazol-1-ide ligands and two water molecules in a trans-CoO2N4 coordination geometry. In the ligand, the dihedral angles between the triazole ring and its adjacent pyridine and benzene rings are 5.57 (14) and 6.89 (16)～, respectively. In the crystal, molecules are linked by O〞H...N hydrogen bonds, generating a three-dimensional network.
